  • Lienhard, John H.; Chung, Hyung Won; Swaminathan, Jaichander; Warsinger, David Elan Martin (Elsevier, 2015-09)
    Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this paper, the performance ...
  • Grogan, Paul Thomas; Shirasaka, Seiko; Golkar, Alessandro; de Weck, Olivier L. (Institute of Electrical and Electronics Engineers (IEEE), 2014-03)
    Federated satellite systems (FSS) are a new class of space-based systems which emphasize a distributed architecture. New information exchanging functions among FSS members enable data transportation, storage, and processing ...
  • Elor, Gilly; Rodd, Nicholas Llewellyn; Slatyer, Tracy Robyn (American Physical Society, 2015-05)
    If dark matter is embedded in a nontrivial dark sector, it may annihilate and decay to lighter dark-sector states which subsequently decay to the standard model. Such scenarios—with annihilation followed by cascading ...
  • Liu, Xiaoying; Jensen, Klavs F. (Royal Society of Chemistry, 2013-04)
    By integrating a heterogeneous oxidation step, gas–liquid separation, and an oxidative amidation reaction to form a continuous system, a multistep synthetic protocol has been demonstrated to produce amides under mild ...
  • Glass, James R.; Saenko, Ekaterina; Livescu, Karen; Darrell, Trevor J. (Institute of Electrical and Electronics Engineers, 2009-09)
    We study the problem of automatic visual speech recognition (VSR) using dynamic Bayesian network (DBN)-based models consisting of multiple sequences of hidden states, each corresponding to an articulatory feature (AF) such ...
  • Winter, Amos G.; Deits, Robin Lloyd Henderson; Dorsch, Daniel S.; Hosoi, Anette E; Slocum Jr., Alexander H (ASME International, 2010-08)
    The Atlantic razor clam (Ensis directus) reduces burrowing drag by using motions of its shell to fluidize a thin layer of substrate around its body. We have developed RoboClam, a robot that digs using the same mechanisms ...
  • Drucker, Andrew Donald (Institute of Electrical and Electronics Engineers, 2009-09)
    In Direct Sum problems |8|, one tries to show that for a given computational model, the complexity of computing a collection F = {f[subscript 1](x[subscript 1]),[subscript hellip] f[subscript 1](x[subscript 1])} of finite ...
  • Schwemmer, M.; Feng, S. F.; Cohen, J. D.; Gershman, Samuel J (Springer US, 2014-01)
    Why is it that behaviors that rely on control, so striking in their diversity and flexibility, are also subject to such striking limitations? Typically, people cannot engage in more than a few—and usually only a ...
  • Jain, Siddhartha; Gitter, Anthony; Bar-Joseph, Ziv (Public Library of Science, 2014-12)
    Reconstructing regulatory and signaling response networks is one of the major goals of systems biology. While several successful methods have been suggested for this task, some integrating large and diverse datasets, these ...
  • Gupta, Rajiv; Chen, Yi; Chang, Jean H.; Greenlee, Alison S.; Cheung, Kenneth Chun-Wai; Slocum, Alexander H. (Institute of Electrical and Electronics Engineers (IEEE), 2010-05)
    In poorly constrained extra-vascular environments such as hollow viscera, current catheter navigation techniques are restricted to simple paths and therefore limit a doctor's ability to position the catheter. This paper ...
  • Kopeikin, Andrew; Ponda, Sameera S.; Johnson, Luke B.; How, Jonathan P. (Institute of Electrical and Electronics Engineers (IEEE), 2012-12)
    A multi-UAV system relies on communications to operate. Failure to communicate remotely sensed mission data to the base may render the system ineffective, and the inability to exchange command and control messages can lead ...
  • Massachusetts Institute of Technology. Department of Mathematics; Poonen, Bjorn; Poonen, Bjorn (Institute of Mathematics, Polish Academy of Sciences, 2010-12)
    For each number field k, the Bombieri-Lang conjecture for k-rational points on surfaces of general type implies the existence of a polynomial f(x, y) [element of] k[x, y] inducing an injection k x k-->k.
  • Lee, Wong Cheng J.; Shi, Hui; Poon, Zhiyong; Nyan, Lin Myint; Kaushik, Tanwi; Shivashankar, G. V.; Chan, Jerry K. Y.; Lim, Chwee Teck; Han, Jongyoon; Van Vliet, Krystyn J. (National Academy of Sciences (U.S.), 2014-10)
    The capacity to produce therapeutically relevant quantities of multipotent mesenchymal stromal cells (MSCs) via in vitro culture is a common prerequisite for stem cell-based therapies. Although culture expanded MSCs are ...
  • Tsoukalas, A.; Mitsos, A.; Mitsos, A (Springer US, 2014-04)
    McCormick (Math Prog 10(1):147–175, 1976) provides the framework for convex/concave relaxations of factorable functions, via rules for the product of functions and compositions of the form F ∘ f, where F is a univariate ...
  • McBee, Megan E.; Zheng, Yu; Parry, Nicola Maria Anne; Nagler, Cathryn R.; Tannenbaum, Steven Robert; Schauer, David B. (Public Library of Science, 2010-10)
    Background: Diagnosis of chronic intestinal inflammation, which characterizes inflammatory bowel disease (IBD), along with prediction of disease state is hindered by the availability of predictive serum biomarker. Serum ...
  • Ooi, Boon Teik; Zheng, H.; Kurniawati, Hanna; Cho, W.; Dao, M. H.; Wei, Jun; Zemskyy, P.; Tkalich, P.; Rizzoli, Paola M.; Patrikalakis, Nicholas M. (International Society of Offshore and Polar Engineers, 2009-06)
    Oceanographic features such as jets and vortices are often found downstream of obstacles and landforms such as islands or peninsulas. Such features have high spatial and temporal variability and are, hence, interesting but ...
  • Wilczek, Frank (IOP Publishing, 2013-09)
    Valid ideas that physical reality is vastly larger than human perception of it, and that the perceived part may not be representative of the whole, exist on many levels and have a long history. After a brief general inventory ...
  • Song, Yale; Davis, Randall; Morency, Louis-Philippe (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)
    Many human action recognition tasks involve data that can be factorized into multiple views such as body postures and hand shapes. These views often interact with each other over time, providing important cues to understanding ...
  • Strnad, Lukas; Peelen, Marius V.; Bedny, Marina; Caramazza, Alfonso (Public Library of Science, 2013-04)
    Cross-modal plasticity refers to the recruitment of cortical regions involved in the processing of one modality (e.g. vision) for processing other modalities (e.g. audition). The principles determining how and where ...
  • Zorzos, Anthony Nicholas; Boyden, Edward Stuart; Fonstad, Clifton G., Jr. (Optical Society of America, 2010-12)
    Optical fibers are commonly inserted into living tissues such as the brain in order to deliver light to deep targets for neuroscientific and neuroengineering applications such as optogenetics, in which light is used to ...
